Is the wife considered sinful if she asks for divorce from her unfaithful husband who does not pray and has no understanding of his religion, especially after numerous attempts to reform him, and her family's refusal of the divorce?

If the husband abandons prayer and commits immoral acts, and does not respond to admonition, then do not hesitate to seek a divorce from him, even if it means waiving some of your financial rights. This is because a woman, like a man, should free herself from someone who neglects the rights of Allah.
